Patent EP-0316557-A3 (EP)
IPC: C09J7/10
Filed: 1988-10-04
Abstract: Ein Schmelzklebstoff mit wenigstens einem Bestandteil, der bei 
Einwirkung von Mikrowellen auf den trocknen Schmelzklebstoff zu 
einer erhöhten Aufheizrate gegenüber einem entsprechenden 
trocknen Schmelzklebstoff ohne diesen Bestandteil und dadurch zu 
einer höheren Aufschmelzgeschwindigkeit führt, weist im Hinblick 
auf einen universellen Einsatz mit möglichst hoher Aktivierbar­
keit und gleichbleibender Eigenschaftscharakteristik als mikro­
wellenaktivierbaren Bestandteil elektrisch leitfähige Substanzen 
auf, deren elektrische Leitfähigkeit über der des trocknen 
Schmelzklebstoffs ohne diesen Bestandteil liegt. Als elektrisch 
leitfähige Substanzen sind insbesondere Kohlenstoffasern, Ruß, 
Graphit, Antistatika und Metallpartikel, entweder allein oder in 
anwendungsspezifischen Mischungen vorgesehen. Schmelzklebstoff­
aufträge oder selbsttragende Schmelzklebstoffolien mit diesen 
Zusätzen weisen eine bis zum Faktor 400 erhöhte Aufheizbarkeit 
durch Mikrowellen gegenüber herkömmlichen mikrowellenaktivier­
baren Klebstoffen auf. Hierdurch ergibt sich eine deutliche 
Verringerung des Bedarfs an elektrischer Energie bei Klebungen 
durch Mikrowellenaktivierung bzw. eine entsprechende Erhöhung der 
Verlegeleistung von zu verklebendem Material. Der neue Schmelz­
klebstoff eignet sich vorzugsweise zur mikrowellenaktivierten 
Schmelzklebung von flächigen Substraten, insbesondere von 
Bodenbelägen, und ermöglicht durch die weitgehende Abkopplung der 
Aktivierbarkeit vom Wassergehalt üblicher Klebstoffe gleichzeitig 
die für industrielle Anwendungen und Fertigungen erforderliche 
Gleichmäßigkeit und Reproduzierbarkeit des Aktivierungs- und 
Aufschmelzverhaltens.

Title: Positive-working photoresist compositions and use thereof for forming positive-tone relief images
IPC: G03C1/72
Filed: 1988-11-30
Abstract: In dry development by selective silylation and dry 
etching, a positive photosensitive resist material 
which is sensitive to a beam of deep UV radiation is 
used to form a positive resist pattern. The positive 
photosensitive resist material contains a resin having 
a phenolic hydroxyl group such as a novolac resin and a 
compound having, within the molecule, an aromatic ring 
having a sulphonyl halide group but not having a 
phenolic hydroxyl group, such as a 1,2-quinone diazide 
sulphonyl halide. A method of forming a positive 
resist pattern comprises coating a substrate with the 
positive photosensitive resist material, exposing the 
determined pattern to the substrate with a beam of deep 
UV radiation, thereafter selectively silylating the 
unexposed region, then dry etching using an oxygen 
plasma with the silylated region used as a mask. A 
fine resist pattern, which is suitable as the mask in 
the semiconductor manufacturing process and has 
excellent dry etching resistivity, can be formed easily.

Patent EP-0330492-A3 (EP)
Title: Active clearance control
IPC: F01D11/08
Filed: 1989-02-24
Abstract: The invention relates to a control system which 
controls the diameter of a turbine shroud which surrounds 
a turbine in a gas turbine aircraft engine. The 
invention seeks to minimize the clearance (33) between 
the turbine rotor blades (123) and the shroud (36). Air 
is bled from the compressor (18) in the engine and ducted 
(98,112) to the shroud in order to heat or cool the 
shroud in order to, respectively, either expand or shrink 
the shroud to a proper diameter. The air temperature 
which is required is computed based on compressor speed 
and other engine parameters, but not necessarily upon 
rotor temperature as such, despite the fact that rotor 
temperature has a significant influence upon rotor 
diameter, and thus upon the shroud diameter needed. In a 
preferred embodiment, air at two different temperatures 
is bled from two different compressor stages (83,89) in 
the engine and mixed together (98) in a ratio which is 
determined (by valve 94) according to flight conditions, 
in order to provide air of the required temperature for 
the shroud, and then ducted to the shroud in order to 
modify shroud size. Further, during accelerations and 
decelerations of the engine, a different air temperature 
is provided, as compared with that provided during steady 
state operation. In the event of system failure shroud 
diameter can be controlled by back up systems, e.g. one 
for use during steady state, and the other for use during 
accelerations and decelerations.
